Meet the scourge of my week: My iPod Nano...

I love listening to music while driving, and being able to listen to j-pop and coldplay and a perfect circle all without having to change the station, miss the end of a song, or listen to the dreaded commercial is dang sweet.

However, my iPod has recently not been turning itself off after being unplugged from its headphones (it should pause and eventually go to sleep, but recently it's been playing right on through), which happens to be the most common way that I let the iPod "shut down," since actually taking the time to grab the iPod, go through the menu system, select sleep, and then reattach the iPod those extra few second that I usually spend doing something else.

My other big annoyance is that I'll frequently find the thing playing... It's like I've bumped it or something and it's started playing when it was off earlier. Recently, I've had to go as far as not only manually putting the iPod to sleep, but also putting the iPod on hold. It's an extra step that I didn't have to take a few weeks ago that now needs to be done diligently to keep the thing operating nominally. ~sigh.

Things just keep getting easier


I've been looking into the next version of Mac OS X Leopard, which is set to include some dang spiffy new features that are destined to move the computing industry right along. The first, and perhaps most relevant for Mac OS X is dubbed Time Machine. Time Machine is a revolution in data backup utilities, making things much simpler and specifically designed for the average PC user, whereas normal backup solutions are usually quite complex to use let alone setup. Time Machine is quite simple to use, basically select the appropriate program that you want restored, lets say iPhoto. Then click on Time Machine in the dock, up pops this very space-age looking user interface, with two arrows on the side: one going "into space" the other going away from it. Basically, going back into the past and coming closer to the present respectively. This isn't exactly easy to explain in words, but Apple has a wonderful video of Time Machine in action at Apple: Max OS X: Leopard Sneak Peak: Time Machine.

The other new things with Leopard is Spaces. Spaces is a feature quite common to Linux users, known as Virtual Desktops in the industry currently. Neither Mac OS X nor Windows derivatives have included Virtual Desktop technology nativly (reports of Windows Vista having the function, but not having it enabled are currently circulating the IT industry), however, this technology has been available as a third-party add-ons for both operating systems starting as early as the 1980s!

Linux has included this feature for quite some time, including some very smooth graphics similar to Spaces in Leopard, thanks to the Novel Xgl technology (Xgl in action, Xgl demonstration videos from Novel). When first released, the Xgl technology made a huge impact in the Linux community, redefining the way newer distributions accomplished desktop switching. However, with recent issues regarding using and distributing the closed-source drivers from nVidia and ATI under the GPL, there have been some setbacks; notably, the Kororaa Linux LiveCD, which was heavily touted as a demonstration CD of the Xgl concept; Kororaa now does not include the drivers for nVidia or ATI, making implementing Xgl on computers with these commonly used cards difficult. There have been some distributions that have successfully worked these closed source drivers into their OS, notably openSUSE, Mandriva, Ubuntu, and Gentoo.

But I digress, Spaces in Leopard (Mac OS X 10.5) should be quite the interesting experience, especially for the Linux/Mac OS users of us out there... It'll be interesting to see the similarities between the two, especially in regards to Xgl. I can't wait to see Leopard in person and really get my hands into the OS.

Vista by-gosh!


At work, Vista is just a name of an OS that we hardly ever see. With Microsoft's release time between Vista and XP being around five-and-a-half years, we still see a majority of Windows XP systems in the store (and a frightening number of Windows 98 systems). But, we have seen a few Vista systems pass though our doors recently.

So far, reports have been bad. With Apple's suggestion of delaying upgrading (for their Windows iPod users), and with the recommendations [more details] for 1 GB of RAM for users wanting to use the Aero interface are just annoying. Mac OS X and it's interface work just fine starting as low as 128 MB of RAM, granted, things are better with more memory, but it's not a requirement like it is in Vista.

The security is quite a concern for me. Bill Gates has recently been quoted along the lines of saying Vista is extremely secure, enough to run as Life Support machines while daring hackers to break Vista. They've hacked Vista already, at least pirated it. Hacking Vista is going to be a chore of the serious hackers and crackers out there, but it is quite possible, and with Microsoft's recent statements of the intense security and the market saturation Microsoft has, I'm betting in a years time, I'll be seeing a rush of virus riddled Vista boxes with customers complaining that "Microsoft said I wouldn't get viruses if I used Vista." Note to everyone reading this blog: if you are using a Microsoft OS (hell, if you are using Microsoft software on your system) get an Anti-Virus... Microsoft software is just attacked too much. It's wise to have an AntiVirus solution anyway, just to be sure that your systems (including non-Microsoft OS systems) aren't filled with virus infected files that could infect Windows boxes that connect to you. For reference, there are free AntiVirus solutions out there:

Windows:

Mac OS X Users:

Linux:


Note: Vista versions may not yet be available. While Avira and Grisoft offer their software for free, they are distributed under an EULA that, from my understanding, requires their software to be used at home or not-for-profit industries. Clam uses the GPL EULA, which includes stipulations against such legal mumbo-jumbo. However, to be sure always read the EULA before installing!

After the release of the OS, I was glad to learn exactly what the OS versions are. Home Basic, to Business, things are looking okay, but Vista Enterprise still is a bit of a mystery to me. I'll have to delve into my IT circles to figure out the details on Enterprise... To a degree, it seems geared to replace Windows Server 2003, which I am throughly trained, however not certified yet... The most annoying thing for me would be to go in to be going through the MCSE process, only to get stopped mid-way by a OS revision.

This is something that Microsoft always does, and it usually does major OS revamps every two to four years, whereas Vista took five to six because of Microsoft's big security overhaul back in the first half of this decade, shortly after the XP launch. I shouldn't bother too much, for the Apple Certified Techs things are much worse, with certs costing ten-times as much as the MCSE, and occurring nearly annually, things must suck for them. However, at least their OS isn't going through such a major change as the XP and 2003 Certifieds are with the change to Vista.

Right after Microsoft releases a new revision to the Windows series, there comes new issues with installing. Not only is this is first version of Windows to be distributed on a DVD (as opposed to a CD), Vista also has a new activation routine. Back in the day, there weren't even product codes! Then came number codes, followed by longer codes, and then random letters were thrown in starting with Windows 98 and 2000. Windows XP upped the ante with activation and product lock outs if the program wasn't activated in a timely fashion. Windows Vista will take the XP activation to the next level, by not only requiring the system to be activated within 30 days, but also limiting functionality during that time frame, finally after the 30 days are up, users are limited to logging in and getting access to Internet Explorer for a period of 60 minutes before the system logs off, allowing no other functionality aside from activation of course.

This activation is unlike anything seen in the "Alt OS" department (dominated by Mac OS X and Linux derivatives), both of which have made it into the twenty-first century, without having such intrusive security requirements... With Apple being around for just as long as Microsoft, one would think Apple would have the same concerns... But Apple seems to trust their users, and the GPL and foundations of Linux in general are for freedom of source, nearly to the point of requiring the OS to be distributed freely.

Worst of all happens to be personified in a recent Apple commercial entitled: Security [caution: QuickTime Video link]. I've actually seen this happen in Vista! It can get quite confusing to the user, especially one not experienced with Microsoft Windows Vista security. I even find it hard to understand why it asks so often to "Cancel or Allow" actions that should be trusted in the first place.

On a side note, I still think it's too early to make a final judgment for or against Vista, only time will tell if the OS will "make or break" the Microsoft empire, but one thing is for sure... There are going to be some interesting times coming up at CyberMedics, as Vista makes its presence known in our humble repair shop... It might not be long before we're all running out to get Vista certified, or OSX, or L+.

A day or two after bringing the cube down to CyberMedics, I was able to head over to Steve's place to check the system out. He had managed to get the full setup for the cube... LCD, Mouse, Keyboard... And USB speakers are being shipped! Swankin'!

This morning, I was working in Firefox on my Linux machine. I had dozen upon dozens of tabs open, I wouldn't be surprised if it numbered close to one-hundred. Well, The Fox has always had a memory leak problem, and even though it's much better these days, there are some things that just cause the browser to balloon, such as flash animations (I've noticed this problem in Windows, Linux and Mac OS versions of Firefox). Well, I was too determined to finish my research to allow a little memory leak to stop me. I was keeping an eye on it, and even though my RAM was maxed out (both the 1.0 GB of RAM and 1.0 GB of swap), I keep trudging on, closing other applications each time my memory (both RAM and swap) got above 95% utilization.

Then ForecastFox attempted to update. Firefox had trapped both my keyboard and my mouse into the browser itself, CTRL + ALT + F1 didn't switch me to terminal, CTRL + ESC didn't bring up KDE System Guard, and worst off, CTRL + ALT + ESC didn't bring up xkill. I was in a bind. I let the PC sit there for a good fifteen minutes... No go.

Then I got an idea... If I could remote in, I could get KDE System Guard up and kill Firefox. I did have the system set up for VNC, so I grabbed my MacBook and attempted to log in; however I couldn't remember what port VNC was on! I was debating on spending time looking the information up on the Internet or just power cycling my system after 65 days... I decided to do neither. All of a sudden, while trying to remember which port VNC was on, I though, I bet I can SSH into Suzi-LNX... But I'll have to get an SSH capable client for Mac OS X.... or is it built in?

HA! It was. I just opened terminal and typed SSH and Suzi's IP address and I was off! I was able to log in and I executed the top command, which lists all the processes on the system (currently Suzi), and noticed that Firefox had indeed maxed out the RAM and swap, taking up over 1.6 GB of memory, when it should never come to that. I immediately killed the PID for Firefox, and turned to see Firefox close on Suzi and the system behaving normally again! Needless to say, I was happy.

* * *


I would like to note that this was a combined fault... Firefox shouldn't have bloated like that, but I also shouldn't have been attempting to work with so many tabs open. Also, there was some tabs with active flash animations going on, which is the frequent cause of Firefox maxing out both RAM and CPU.
